precipitation echo

基本解释

The results can help analysis echo of multi-wavelength and understand process of cloud precipitation correctly.
在实际工作中，分析多波长雷达的回波时，这些讨论结果对分析和理解云降水过程有帮助。
It is shown from analysis that the Precipitation ahead of cold front was about 92% of total surface rainfall, and made of four echo clusters.
结果表明：冷锋锋前的降水约占全部降水的92％，锋前降水由四个回波团组成。
Non-precipitation echo from radar such as ground objects echo and super refraction and so on are important to explore quantitatively precipitation and the other products.
地物和超折射等非降水回波是影响雷达定量探测降水和其他产品的重要因素，利用降水和非降水回波反射率三维结构特征可以对雷达数据进行质量控制。
